Hand Tightenable Device For Holding A Cutting Implement
US Patent:
4660841, Apr 28, 1987
Filed:
Jan 14, 1985
Appl. No.:
6/691443
Inventors:
Michael J. Chouinard - Milton MA
International Classification:
B23B 3100
B23B 522
B23B 522
US Classification:
279 61
Abstract:
A hand tightenable chuck for holding a cutting implement in place has been developed. The chuck uses two screw systems to achieve the proper degree of tightness; a first system providing a coarse tightening or pinching of the shaft and a second providing a clamping action. The combination of screw systems eliminates the need for the key used to tighten conventional chucks.
Method And Apparatus For Disassembly Of A Spot-Welded Structure
US Patent:
4644656, Feb 24, 1987
Filed:
Jun 8, 1984
Appl. No.:
6/618574
Inventors:
Michael J. Chouinard - Milton MA
International Classification:
B26F 100
US Classification:
30362
Abstract:
A method and apparatus for removing spot welds from a sheet metal structure is shown. A fluid powered hand punch has a handpiece and an L-shaped extension forming a punch die. An elongated rod extends from a fluid piston within the handpiece to a punch bit, allowing the punch to be conveniently positioned over spot welds in diverse structures. An extension of the handpiece body guides and stabilizes the rod. Spot welds are removed by positioning the punch bit over the weld and entirely punching it out. A tapered punch bit engaging the metal along a partial perimeter of its front face is also shown.
